Belt Driven Downblast Ventilators

Dayton downblast ventilators provide a clean air supply by exhausting harmful gases in commercial and industrial spaces. These ventilators are powered by an AC motor rotating fan blades with the help of a belt drive. The durable aluminium construction can withstand severe exhaust conditions, while a fully rolled windband bead provides stability. They are equipped with neoprene isolators to isolate the drive frames from rest of the unit for prolonged life. Choose from a wide range of these belt-driven downblast ventilators, available in speed ratings ranging from 214 to 1800 RPM on Raptor Supplies.

Direct Driven Downblast Ventilators, Roof Mount

Dayton downblast ventilators are roof-mounted for discharging dirty air from industries and commercial buildings. They are designed to operate continuously to vent foul air and odour under low to moderate static pressure conditions. They have spun aluminium construction with a fully rolled windband bead for corrosion resistance, durability, stability and portability. These ventilators feature direct driven motors that are directly connected to the fan through shafts or axles, thereby increasing energy efficiency. Selected models come with a speed control for controlling the speed of ventilators. Choose from a wide range of these ventilators, available in wheel diameters ranging from 8.25 to 18.5 inches.

Downblast Centrifugal Roof Ventilators

Downblast centrifugal roof ventilators are roof or wall mounted for discharging dirty air from industries and commercial buildings. Raptor Supplies offer centrifugal roof ventilators from brands like Dayton and Fantech. They operate continuously to vent foul air and odours under low to moderate static pressure conditions. Raptor Supplies provides centrifugal supply ventilators in two types, namely belt driven and direct driven. Belt driven downblast ventilators offer greater flexibility in terms of rpm speeds as the motor is not directly in contact with the fan's moving parts. Direct driven downblast centrifugal ventilators are designed such that the motor is directly connected to the fan through shafts or axles, thereby increasing energy efficiency.
